This story is a bit misleading. I just saw an I/O Drive Octal at the Brighton MS SQL show and it's just one card. I understand it has 8 modules but the Virident card has 20 modules. I assume the Virident card comes default as one volume. Unlike the Fusion I/O card which I was told comes default as different volumes so we can decide what to RAID together. So other than different default settings the facts are that the Octal gets to 1 million IOPS from a single PCIe slot and Virident takes two PCIe slots.
Not picking sides here just trying to clarify what seems to be a confusing and possibly misleading story.
